WRINGER.

Application led May 20, 1921.

T o all whom t may concern Be it known that I, EDGAR D. M1sNnRa citizenof the United States of America, residing at Detroit, in the county ofWayne and State of Michigan, have invented cer faces terminating inoff-set steps for cooperating with the rotatable tensioning mem ber tomove the movable roll of the wringer toward the other upon rotation ofthe tensioning member and to hold the same in either of its adjustedpositions. The invention has for another object, the provision ofequalizing means for facilitating the simultaneous and equal movementsof the opposite ends of the movable roll when moving away from the otherroll. Further objects of the invention reside in the novel features ofconstruction as more fully hereinafter set forth.

In the drawings:

Figure 1 is a side elevation partly broken away and in section, of awringer 4embodying my invention;

Figure 2 is a top plan view thereof;

Figure 3 is a cross section on the'line 3-3 of Figure 1;

Figure 4 is a bottom plan View of the stepped cam member;

Figure 5 is a cross section on the line 5--5 of Figure 2.

l is the frame of the wringer formed of the complementary sections 2 and3 which are suitably secured to each other as by means of the machinescrews 4. 5 is the power driven roll and 6 the cooperating roll. Theshaft 7 of the power driven roll is rotatably mounted in bearing blocks8 at its opposite ends which are positioned between the complementarysections 2 and 3. 9 is a gear secured to one end of the shaft 7 andadapt- Serial No. 471,136.

ed to mesh with the gear 10 secured to the corresponding end of theshaft 11 of the cooperating roll, these two gears being inclosed withinthe enlargement 12 formed upon the complementary sections 2 and 3. 13are bearing blocks located at the opposite ends of the shaft 11 andslidably engaging between -the complementary sections 2 and 3 of theframe.

The bearing blocks 8 and 13 are preferably formed of wood andimpregnated with lubricant, each having the half bearing 14 forengagement with the shafts.

15 is a resilient bowed member extending above the cooperating roll 6and having its ends engaging in rectangular apertures 16 in the upperend of the metal strips 17 which are at the inner sidesof the bearingblocks 13 and have circular openings 18 near their lower ends forengagement with the shaft 11, these circular apertures being of suffi--cient diameter so that when the cooperating roll 6 is moved toward thepower driven roll 5 by means of the ends of the resilient bowed membercontacting with the t"ops of the bearing blocks 13, the shaft 11 willcontact with the half bearings in the bearing blocks 13. 19 is atensioning rod extending transversely of the resilient bowed member 15and longitudinally movable in the cam member 20 secured centrally to thetop ofthe frame 1. This tensioning rod is secured at its lower endltothe clip 21 by means of the screw 22 threadedly engaging the clip andextending into the annular groove 23 in the tensioning rod. The lowerportion of the clip is U-shaped to embrace the center of the resilientbowed member 15. l

. For the purpose of facilitating the movement of the cooperating roll 6toward the power driven roll 5, the cam member 20 has the pairs of camor inclined faces 24 and 25 at the lower ends of which are the shouldersor steps 26 and 27 respectively, and the tensioning rod 19 has thetransverse projection 28, which is preferably a pin, extending out fromone side thereof for engagement with these inclined faces and st ps, theparticular face and step being depen ent upon the direction of therotation of the tensioning rod. The transverse pin 28 is normallybetween the upper ends of the inclined faces when there is no tensionupon the resilient bowed member-15 so that this pin is in position toengage the inclined faces and to ride down over the same upon rotationof the tensioning rod to place the resilient bowed member under tensionand to move' the cooperating roll 6 toward the power driven roll 5 bymeans of the bearing blocks 13. The steps 26 and 27 are at differentheights so that a differentv predetermined tension is placed upon theresilient bowed member when the transverse pin is in engagement witheach of these steps.

To release the pressure of thecooperating roll upon the power drivenroll it is merely necessary to rotate the tensioning rod 19 to disengageits transverse pin 28 from its engaged step, when the pin will ride upover an inclined face. The handle 29 is provided at the upper end of thetensioning rod for rotating the same to move the cooperating roll 6toward the power driven roll or for disengaging the transverse pin fromits engaged step and to prevent vrotation of this handle upon releasingthe pressure, and after the transverse pin 28 has moved over an inclinedface, the upper portion of the cam member 20 has the diametricallyopposite slots 30, the walls of which connect into the upper ends of theinclined faces.

To facilitate'the simultaneous and equal movements of the opposite endsof the cooperating roll 6 when moving away from the `power driven roll5, the lower end of the tensioning rod 19 has the recess 31 to receivethe coil spring 32. Vhen the tensioning rod is in either of itsinnermost positions to tension the resilient bowed member 15, the latterrests against lthe lower end of the tensioning rod; but when themechanism is tripped, the spring 32 will clamp the resilient bowedmember against the base 33 of the U-shaped portion of the clip 21` whichbase forms an extended bearing for the resilient bowed member andthereby prevents rocking movement of the resilient bowed member relativeto the tensioning rod. rIhis resilient bowed member is preferably formedwith the lug 34 which is engageable within the lower convolution of thecoil spring 32 to longitudinally7 position the resilient bowed member.The bearing blocks 13 also preferably have their sides slightly taperingto avoid too great a vfrictional resistance to their movements.

To limit the upward movement of the cooperating roll 6 when themechanism is tripped, the complementary sections 2 and 3 of the wringerframe are spaced apart a distance less than the diameter of thecooperating roll and have the transversely extending fianges 35 whichare adapted to be engaged by the cooperating roll. To drain any'waterwhich drops ofi` the ends of the rolls inwardly away from the ends ofthe wringer frame, there are inwardly extending and downwardly inclinedianges 36 beneath the power driven roll.
